BORING-MACHINE.

Specification of Letters Patent.

Application filed May. 19, 1910.

Patented Feb. 21, 1911. Serial No. 562,218.

a machine which will have a very large,

capacity and in whicheach boring tool will have ample time. to do its.work without crowding and: consequent injury from over heating To thisend the invention consists inproviding one or morerotatable-toolcarrying heads having radial boring tools and a holder rotatable withsaid. head or heads to receive and hold the work in alinementwiththeseveral tools as saidheads are rotated.

The invention further consists .in providing means for feeding the workto theutools and automatically discharging thesame, and in providingcertain other new. and useful features in the construction andarrangement of parts, all as hereinafter more fully described.

reference being had to the accompanying drawings in whlch,

Figure 1 is an end elevation of a machme embodying the invention; Fig. 2is a front elevation of the same with parts in section to show theconstruction; and Fig. 3 is an enlarged detail of the carrier disks andmeans for feeding slats thereto.

In the drawings 1 represents a suitable supporting frame provided withbearings for a shaft 2 extending horizontally acrossv the same and uponwhich shaft are mounted two circular heads 3 adjustably, secured to,

the shaft by. means of keys 4 to turn therewith. These heads are eachprovided. with bearings 5 and 6 for a series of radially extendingspindles 7 to the outer end of each of which'spindles is secured aboring tool 8 and upon each spindle between said bearings is secured abeveled. pinion 9 by means of which said spindles are rotatedin theirbearings and held against longitudinal movement therein. Each head isalso provided with a laterally extending sleeve portion 10 severalspindles to simultaneously turn said spindles.

The pulley-1ljofeach head with its gear 13 is driven by means of a belt:14 engaging thepulley and also a pulley 15'on a driving shaft 16 mountedin bearings on the machine. frame and extending horizontally across thesame near. the bottom thereof. Theshaft. 16 is driven in'any suitablemanner, as by-power appliedto a driving; pulley 17 secured upon one endthereof. Secured to then-opposite end of said shaft is a pulley 18 fromwhich motion is transmitted by a belt 19 to a pulley'20 upon a shortshaft 21 mounted in hearings. on the machine frame. Froma small pulley22 on the shaft 21 slow motion is transmitted by a belt 23 to a largepulley 24 mounted upon a short shaft 25 adjacent to one end of the mainshaft 2. This shaft. 25 is provided with a pinion. 26 in mesh with alarge gear 27 se cured to the end of said shaft 2 and thus said shaftupon which the heads 3 are mounted is turnedwith a slow motion.

Secured to the adjacent faces of each of the-two heads 3 are two disks28 and 29-by bolts 30 extending through slots in said disks. Each diskis provided with a series of notches in its periphery forming radiallyextending fingers 31 on the disk 28 and similar fingers 32 of lesserlength on the disk 29. Guide ways 33 leading from a table or similarsupport 3 1 for a supply of slats 35 to be bored, are adjustablysecuredto a rod 36 which in turn is adjustably carried by brackets 37adjustable vertically upon posts 38 bolted to the machine frame at oneside of the heads 3. The slats are caught as they pass out of the lowerend of the guides 33, one at a time, by bars 39 having hooked lower endsto hold the slat in position to be engaged by the fingers 31 as theheadsare turned and lift the slat off from the bars. These bars 39 areadjustably secured to the guides 33 by bolts 40 extending throughlongitudinal slots in the bars so that said bars may be adjustedlongitudinally according to the width of the slats 85. The disks '28 and29 are adjusted relative to each other so that there will be spaces 41between the fingers 31 and 32 just wide enough to receive one of theslats 35 edgewise and the disks are adjusted so that these slots willcome oppositethe boring tools 8 and thus when the slats 35 are liftedfrom the hooks 39 and slide edgewise inward upon the edges of thefingers 31, they will engage the ends of the too? in proper position tobe bored by said too s.

Extending horizontally across the frame vertically abot e the shaft 2and the heads 3 thereon, is a supporting rod 42 mounted at its ends inbearing members 43 which are adjustably supported by brackets 44 mountedupon the ends of the machine frame. This rod may be raised or lowered byadjusting the bearing members 48 upon the brackets 44, said bracketsbeing provided with slots to receive bolts 46 for securing the bearingmembers thereto. Supported by suitable hangers 47 to the lower ends ofwhich they are bolted, are semi-circular guide bars 48 and these guidebars are suspended bythe hangers 47 adjacent to one side of the fingers31. Each guide bar is also so supported that its inner edge will beeccentric to the head and is so held that as the slats are carriedupward from the supporting hooks 39 by the fingers 31, they will engagethe inner edge of each guide bar 48 and by reason of the eccentricposition of said guide bar will be forced radially inward in the slots41 by said bars, forcing the slats inward upon the boring tools whichare thus caused to bore the desired holes therethrough. The bars 48 arecurved at one end as at 49 so that the slats will readily pass under thebar and at their opposite ent s said bars are each held by a link 50pivot-ally attached thereto and to a lug on a clip 51 adjustablysecured-to a bar extending across the frame. Extending across themachine frame at the opposite side of the heads 3 is a rod 52 upon whichis mounted arms 53 adapted to be slid longitudinally of the rod andsecured in their adjusted position by set screws 54 with their upperends adjacent to the outer periphery of the heads 3 and in line with theguide bars 48 so that when the slats have been carried over to the rearor discharge side of the machine by the turning of the heads and havebeen forced inward upon the tools by the guide bars 48 and bored, theywill come in contact with the arms 53 which will engage their inneredges and by reason of the inclination of said arms will be lifted fromthe tools and fall from the slots 41 between the fingers of the disks.To engage each end of each slat as it is carried upward from the end ofthe feed guides 33 and center said slat endwise relative to said heads,semi-circular plates 54 are held in proper position relative to theheads by bars 55 to which they are bolted, said bars 55 being adjustablysupported at their upper ends upon the rod 42 and at their lower endsupon the rod 36.

The boring tools are driven at a high rate of speed by means of thegears 13 driven by the pulleys 11 and the heads are turned at the sametime with comparatively slow speed by power applied to the gears 27. Theslats are thus bored while they are being carried from one side to theother of the heads, said slats being gradually forced inward upon theboring tools by the guide bars 48 and thus each tool is given ample timeto do its work without forcing the work too rapidly into engagementtherewith and overheating the tool. The arrangement of a rotatable headprovided with radial tools and also with means for carrying the work,permits of the boring of a large number ofslats at one time, thus givinto the machine a great capacity and provi ing a very simple and compactarrangement.

The heads 8 may be adjusted upon their shaft 2 for different lengths ofslats and also to bore the holes at any desired distance from the endsof the slats or any desired distance apart. If it is desired to boremore than two holes in each slat other heads similarly provided withboring tools may be placed upon the shaft and if it is desired to borebut one hole in each slat, one of the heads may be dispensed with, thedisks being otherwise supported upon the shaft, or other suitable meansmay be provided for holding one end of the slats.
